Abstract: A drilling machine capable of rapid change over for drilling different parts, and which has stations for simultaneously, or sequentially, drilling holes in a particular part. The unit includes means for positively positioning the part, and gripping the part, and rotating or indexing the part to different rotational positions for the drilling operation. Control means are utilized for positively and precisely positioning the part for the various drilling operations.

Abstract: A continuous motion assembly machine for assembling parts which require rotary assembly motion such as putting together two threadably assembled parts. The machine includes a plurality of assembly devices mounted on a rotating support which are operated as they rotate to pick up a first part, and to provide inspection of the parts, which in the form shown is the presence or absence, proper position and proper fit of parts, and assemble the parts and reject any parts that are improperly assembled, remove the good parts, and repeat the cycle. The assembly is carried out with rotary assembly motion between the two parts and which rotary motion can be controlled at a desired torque level for insuring proper assembly and operation of the parts.
